V is the wave speed in metres per second ms. Where v is the velocity of the wave. The Wave speed formula which involves wavelength and frequency is given by.
Calculate the frequency of the wave.
V is the wave speed in metres per second ms. V equals 4 start fraction start text m end text divided by start text s end text end fraction. Multiply wavelength by the frequency of the wave. In equation form If the crest of an ocean wave moves a distance of 20 meters in 10 seconds then the speed of the ocean wave is 20 ms.
